IMPROVED SHUTTER-FASTENING.

. Specification forming part of Letters Patent No. 117,71 l-datedv May16, 1865.`

-ToaZZ whom it may 'concea y Be it known that I, JACOB FRIGK,oilPhiladelphia, Pennsylvania, have invented an ImprovedShutter-Fastening; and I do hereby declare the following to be a` full,clear, and

exact description of the saine, reference being In ordento enable othersto make and use "any invention, I will now proceed to 'describe itsconstruction and operation.. y

y 0n reference to they accompanying drawings, which forni a part of thisspecification,I

Figures l and 2 are views of my improved shutterffastener, showing the4parts in diii'erent positions; Fig'. 3, a view partly insection looking4in the direction of theiarrow, Fig. 1 and Figze, a detached sectionalview.

iimilarletters referlto similar parts throughont theseveral views.

A is a plate, which is securedtc the side of one shutter, near the edgeof the same, and adjacent to a somewhat similar plate, B, which issecured to the other shutter.

On Qtheplate A are the curved rib b and straight rib c, and between thetwo Ais an oblong opening,`X.

0n theinside of the plate A, on each side of the opening X, is aninclined projection, d, y the two projections being beveled inoppositedirections,as shown in Fig. 3. l

the. lower portion of the plate Bis an oblong opening, X', and in thecenter of the plateis a' pin, e, to which is hung one end of 'an arm, D.Through the arxn D, near the outer-end of the saine,passes a rod, E,onone I j 'l end ci 'which is a'handie, j', and on the other Y endemi"shaped head, -y,'the lattei` being so `cnt as to form two beveledshoulders, w x,

adapted 'te the inclinedfprojection d d, as

. shown inFig. 3.

' 0n the arm D is a semicireular or nearly semicireular rib, t, forlimiting the movement of the rib Z.

an'opening'inithe head g of thespindle- Y E is inserted a block ofrubber'or leather, and similar bloelrs'ofrubber or leather are alsoinserted in recesses in the under side of the arm D.: From the rib cprojects a pin, k, for limiting the upward movement of the arm D.

When the shutters have to be fastened they 4 are brought together, thearm O -is raiseduntil it strikes the pi-nK, the handle f of the spindleVE is brought to aV position at rightV angles to that shown in Fig. 2,and the spindie is then pushed forward, so that itshead may pass throughthe opening X inthe plate A. The handlef is then turned to the positionshown in Fig. 2,- when the inclined shoulf ders a: of the head will bebrought in contact with the inclined projections d d on the under sideof theplate A, the spindle being thereby drawn inward yso as yto confine`the end of the arm D tightly between the handle f andthe ribs b andA con the plate A, thus secar:

ingthe two portions of the shutter `.firmly together. Y

To'unloch the fastening it is only necessary i `to turn the handle f tothe positionshown 1n dotted lines, Fig. 2, and pull it outward, there-`by withdrawing the head of the spindle E from the opening X, when thearm D will fall by its own weight to the position shown in Fig. 1. Thehead of the rod E may then be `introduced into the opening K', thehandle being brought to the position shown in Fig. 1,

' so as to lock the arm to the plate B. By thein'troduction of blocks ofrubber or other elastic material'into recessesA in the end i of the headg and in recesses in the arm D these 'parts' are prevented from cuttingor scratching the plateB as. they move over the latter, and also servethepurpose of preventing the disagreeable rattling of the shutters.

It will 'be seen that in1 the device there are no parte which can beinjurionsly aiiected by exposure to the weather, there being no springsand other appliances liable to getout of order, and that the device issimple and efficient in its operation. L l

1t should be understood that the slot X is considerably larger than thewidth of the head g, so that the shrinkage of one or both of theshutters may not .render the fastening nnserviceable. i

I claim as my invention and desire to'secure v shutters, substantiallyes and for the purpose herein set forth. In testimony whereof I havesigned my name to this specification in'the presence of two subscribingwitnesses.
